Subject: [PATCH 1/1] i2c: add HAS_IOPORT dependencies
Date: Thu,  4 Apr 2024 16:33:51 +0200

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them.

Note: This patch does not depend any not-yet-mainline HAS_IOPORT changes
and may be merged via subsystem specific trees at your earliest
convenience.
